I cobbled together a diagram based on the Duncan J bass with push-pull series-parallel and a diagram for a bass cut pot. Anyone care to proof my drawing before I start soldering?

So close. Double check wiring for the Bass Cut control. That's the only issue I see.

Or I could give you an answer, if asked. Be aware, the correct answer will cost $100.

It's missing a jumper across 1st and middle or 3rd and middle lugs depending on which direction I want to turn to cut now that I'm looking at a few different diagrams.

No, sir, not a jumper. Just one existing wire needs to be relocated.

Here's how it's currently wired. I added terminal lug numbers, 'cause it helps me keep things sorted.:

And schematic wise, with pot terminal numbers, here's how it should be wired. Wire-by-numbers (kinda like paint-by-numbers LOL):

I promise this is the last time I hold off the answer, 'cause I know you want to get this soldered and working again. I won't even charge my usual fee LOL.
 
Based on that, I think it's bass cut 3 to tone pot 2 instead of bass cut 2 to tone pot 2. I'm not particularly numbers minded which is why I drew everything out in different colors.

I'm traveling for work so I won't be able to tackle this until next week some time. Who knows if it'll even be a value-add for the bass I'm putting it in. It's currently active with a terrible preamp and 4 pots, so I wanted something to fill the 4th spot that wasn't a typical tone control but also doesn't require any atypical components.

That's it!

I didn't know you were in a work related time crunch, so I apologize for the delay. The value of the Bass Cut may show up when switched to series. Sometimes that can get a bit bass-y.

Hope you let us know if it's a keeper circuit or not when you have the time.

Not really a time crunch, happy to take my time to gain more knowledge before jumping into projects. Especially when there are so many different variations of similar circuits online.

I have a bass cut control in one of my Bass VIs and love it there, makes it sound more like a big ol' guitar. This one is going into an octave-course 10 string, so it could make for some pretty interesting tones.
